DuPont plans buyback of up to $2 billion in stock

WILMINGTON, Del. 
DuPont says its board has authorized a buyback of up to $2 billion of its common stock.

This program will begin after the company's purchase of about $500 million still remaining under a previous buyback program is completed.

The Wilmington, Del., chemical company on Wednesday also declared a second quarter common stock dividend of 41 cents per share. The dividend is the same as the first quarter and is payable on June 10 to stockholders as of May 13.
